Description

This functional eye model provides an effective way to demonstrate the working principles of human vision. The movable retina allows the eye?s shape to be altered, while the silicone lens and ciliary body enable changes in lens form and thickness. Images can be projected onto the retina to illustrate key optical concepts, including:

• Lens accommodation
• Near point of vision
• Myopia (nearsightedness)
• Hypermetropia (farsightedness)
• Presbyopia
• Correction of vision defects using lenses or glasses
